REVERSIBLE-WINDOW CHECK.

Application filed November 3, 1927. Serial No. 230,800. 7

This invention relates to reversible windows, of that type in which the sash swings on horizontal pivots, being pivotally hung between side arms which are pivoted at their upper ends to the casing and at their lower ends to the sashes.

The object of the invention is to provide improved sash supporting arms, provided with springs to cushion the action of the sashes as they are swung open or closed. 7

Various other improvements will be evident from the following description and the accompanying drawings in which Fig. 1 is a sectional view of the window taken on line 11 of Fig. 2. Fig. 2 is an elevational view of the window as seen from the inside of the building. Fig. 3 is a cross section thru the sash and frame on the line 3-3 of Fig. 2. Fig. 4 is a sectional diagram showing the installation and operation of the window. Fig. 5 is a detail view of the upper arm, partially in section and Fig. 6 is an elevation view of the lower end of the arm shown in Fig. 5.

A window casing consisting of the head 1, the j ambs 2 and sill 3 is made to fit the opening in the wall of the building. A metal channel 4 is secured within a recess 5 plowed into each amb 2 and extends the entire length of the frame between the head 1 and the sill 3, and has holes in it at intervals into which a bullet catch or spring-actuated plunger 14 fits. As the sashes are opened the catches snap into and out of the holes, and will hold the sashes in desired position.

The outside trim 6 and 6 act as stops for the upper and lower sashes 7 and 7 and have strips 8 and 8 fastened to them and are rabbeted to receive weather strips fastened to the sashes.

' The catches 14 form pivots for the sashes, that of the upper sash being indicated in the diagram Fig. 4 at 9, and that of the lower sash at 10, the fixture consisting of a piece having a flat portion 11 which is fastened to the lower edge of each sash by screws 12 and a cylindrical portion 13 which forms a hou s ing for the bullet catch or spring detent pm or pivot 14. The outer face of the sash has the weather strips 15 and 15 fastened to it at the top and sides respectively by means of screws in elongated holes. The elongated holes allow the strip to'be adjusted. When the window is closed the weather stri fits into the rabbet aforementisned and against strips 8 and 8 forming a weather tight joint.

One of the arms for holding the upper sash is shown in Fig. 5, in which 16 is an L shaped casting or forging which is fastened at the top of the sash to the window frame by screw at 17 and which is free to swing on the screw. This casting is connected by a rod 23 to a tube 18 which encloses coiled springs 19 and 20 which are retained between the plugs 21 and 22 which are fastened in the tube. Plug 22 has a hole in it thru which rod 23 passes which is screwed into the lug 24 of the arm 16. The end of the rod is peened over to prevent it getting loose. The spring 19 fits over the shank of the rod 23 between the head 25 and the plug 22 andthe spring 18 is confined between the head 25 and the lower plug 21, which has a hole 26 in it thru which a screw passes to pivot same to sash 7 at about the middle of the latter.

Each of the lower pair of arms 50 for the lower sash is pivoted to a plate 27, fastened to the jamb by screws 28 and the channel shaped arm 50 is pivoted at 29 to said plate and pivoted at its lower end to the sash 7 at 30. The sash is free to pivot at this point. At its upper end the arm has a hub 31 and a boss 32. The plate 27 has a similar hub 33 and boss 34: formed integrally with it. A spring 35 is wound around said hubs and the ends of this spring are fastened to the bosses just mentioned.

The springs in both theupper and lower arms are compressed by closing the sash in either reversed or normal position and prevent the sash from slamming. In the upper arms the springs expand and contract. Those 1 in the lower arms are put under tension.

A metal glass stop 36 is provided at the top of each sash and is so shaped as to hold a shade roller at its ends and protect. the window shade when the window is washed, the stop having a curved flange 61 for that purpose. The glass is shown at 62.

- A lock for'the upper sash consists of the lever 37 to operate the lock and act as a window hook and it is pivoted at 38 and engages the slotted catch 39 which slides up and down to engage a cross bar 63 at the top of the easing. The hub 40 is flattened at 4L1 and 4:2 to prevent excessive movement of the lever. The ower end terminates in a oke 43 which hasa as at side into wnieh a detest pin 48 fits holding the lever in position when the window is locked. An eccentric window shade cord holder 46 for the cord 64: rotates on the outer surface of the spring detent pi shell 45 as an axis. j

Both sashes are rabbeted for the arms and are cut away at the top and bottom where the arms come thru. An ordinary catch 66 may be used to hold the lower sash closed.

The operation is as follows:

To open the upper sash the lever 37 is swung out at the bottom thereby releasing the .catch 39 and permitting the upper end of the sash to swing outwardly, or into the room, as

shown in dotted lines in Fig. 4, the spring pivots 1 L sliding up in the channels 5 and slipping into and out of the holes in said channels. The arms swing with the sash, on the pivots 17, and the springs 18 and 19 pre vent slamming, or cushion the action. The sash may be swung to horizontal position or completely reversed if desired. As to the lower sash, by releasing the catch 66, it may be swung out in the same way, the arms 50 swinging with it, the action being eased or cushioned by the springs 35 which are put under tension by the pivotal movement.

After the upper sash is closed it may be locked by swinging down the lever-37, which lifts the catch 39 to engagement behind the bar 63. The cam device 46 afior-ds a convenient means for holding the sash cord 64:

in any desired position.

Various changes may be made in the detailsof the structure within the scope of the following claims.

I claim:

1. A reversible swinging window comprising a sash and a pair ofarms pivotally connected to the window casing and the opposite sides of the sash, and between which the sash will swing, each of said arms being provided with oppositely acting spring means enclosed therein to permit elongation or contraction of the arms.

2. A swinging window as set forth in claim 1, the spring means including oppositely acting springs enclosed in each arm and adapted to be placed under tension by the swinging movement of the arm.

In testimony whereof, I do aflix my signa ture.
